Application filed Mar-ch 16, 1914. Serial No. 825,018.

To all whom it may concern:

Be it known that 1, JAMES 700D, a citizen of the United States, and a resident of Noblesville, county of Hamilton, and State of Indiana, have invented a certain new and useful Machine for Forming Heel- Calks on Horseshoes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

This invention is an improvement over that shown in my former Patent, No. 1,055,006, dated March 4, 1913.

The object is to improve the operation of the machine in forming the heel calks of horseshoes and to facilitate the placing and replacing of the die.

The nature of the invention will be understood from the accompanying drawings and the following description and claim:

In the drawings, Figure 1 is a perspective view of the machine. Fig. 2 is a central vertical section through the upper part thereof. Fig. 3 shows a portion of Fig. 2 in operated position. Fig. 4 shows a modified form of a portion of Fig. 3.

There is shown in the drawings herein a horseshoe heel calk forming machine with a main frame formed of the base 10 and a pair of upright frame plates 11 spaced apart so that the machinery can be placed between them. A pair of extensions 12 project horizontally from the upper part of said side plates 11, as shown in Fig. 2, and they carry a block or anvil 13 integral with them, and the dies 14 are inserted and held in vertical slots 114 in said extensionsv 12. The dies have bevels of various types, as shown in Figs. 2, 3 and 4. The horseshoe 15 is placed in the block 13 and die 14, as shown in Fig. 3, and then a horseshoe holder 16 is brought down upon said horseshoe to hold it in place, as shown in Fig. 3. This. holder consists of a horizontal plate 16 After the horseshoe has been put in: place,

it is formed in coiiperation with the die by the downward movement of a hammer or block 25, which is removably secured to a aw 26 pivoted at its rear end on the rod 27 which extends through the frame plate 11. .The jaw has a triangular recess in its lower left-hand-corner for receiving the hammer 25, and said hammer has a rear- -ward1y extending pin 28 projecting into a corresponding hole in the jaw 26 and it is held there by a set screw 29, and by releasing the set screw 29 the hammer 26 can be withdrawn and another one put in its place. The jaw extends above the hammer 25 so as to reinforce it when the jaw is brought down, and the lower left-hand corner of the hammer 25 is beveled at 30 so, as

it comes down on the heels of the horseshoe,

said hammer breaks down the metal against the bevel surface of the die 14, as shown in Fig. 3. WVith this arrangement the horseshoe holder 16 is not in the way of the hammer and the hammer can be changed as desired.

The aw 26 is actuated by a bar 31, which is pivoted at its upper end thereto and at its lower end is pivoted to a lever 32 fulcrumed between its ends on the pin 33 in the frame plates 11. A connecting bar 34 runs from the rear end of the lever 32 to an arm 133 rigidly secured on the rod 34 mounted loosely in the upper rear portion of the frame plates 11, and a hand lever 35 is rigidly secured to said rod, so that when the hand lever is moved to the left, as shown in Fig. 1, the intermediate mechanism just described will draw the jaw down from the position shown in Fig. 2 to that shown in Fig. 3. i

The set screw 40 in the lower part of the jaw 26 is in the nature of a stop against which the heel of the horseshoe is placed when it is introduced into the machine. At that time the set screw 40 is at its upper position, as shown in 'Fig. 2, and the heel of the horseshoe abuts against it.

Any form of die 14 can be readily dropped into the machine, and three forms are here shown. The preferable form of die is that shown on an enlarged scale, in Fig. 4, having a projecting rib-like overhanging portion 40 at the upper corner thereof and then an outwardly and downwardly inclined surface 41 so as to form a calk with a recess at the joint between the calk Specification of Letters Patent. P ted July is, I

and body of the shoe, as indicated in Fig. 4. The purpose is to insure the bend between the ealk and body of the shoe to be at least square. When the corner of the die is absolutely square, the angle between the calk and the body of the shoe will never be square but somewhat obtuse. With this arrangement, the shoe will come out with the ealk extending at a right angle from the body of the shoe or slightly obtuse angle approaching closely a right angle.

The invention claimed is:

A machine for forming calks on horseshoes including a frame, an anvil block, a die on which the horseshoe may be placed, means for treating the horseshoe to form the calk, a horseshoe holder adapted to hold the horseshoe on the block and anvil and having downwardly extending side bars, a pedal lever to which the lower ends of said bars are pivoted, and bars pivotally connectingsaid holder side bars to the frame to mount and hold them in their vertical movements.

In witness whereof, I have hereunto affixed my slgnature 1n the presence of the witnesses herein named.
